This paper examines humans' cognitive characteristics toward home robots within the home environment over the course of a 16-day-long experiment. We adopted a semi-structured interview format to three families after the experiment and a conversation log with robots which have voice recognition system was analyzed for one family. For the conversation log, time-series analysis has been conducted in order to investigate the change of cognitive characteristics toward the home robot over the passage of time. The results indicate that(a)users get accustomed over time to the home robot and attachment emotions are elicited by living with the robot,(b)users emotionally communicate with the home robot by the touch interface, and(c)users gradually come to understand how the robot works and to construct a companion model for the robot as a sort of a mental model, which is an internal model for how something works.
